Ah yeah, we're sourcing that file to import the DROPBEAR_OPTIONS (since
2015.70-1) or PKGOPTION_dropbear_OPTION (since 2014.64-1) environment
variables. The initramfs-tools maintainers have now (cf #807527)
written on best practicing for configuring hooks:
“If a hook script requires configuration beyond the exported
variables listed below, it should read a private configuration file
that is separate from the /etc/initramfs-tools directory. It must
not read initramfs-tools configuration files directly.”
— initramfs-tools(8)
So I guess we'll use an DROPBEAR_OPTIONS variable in
/etc/dropbear/initramfs-tools.conf or something. But it's not yet clear
to me how to do such migration in a way that doesn't break existing
installations.
